Gents, I have tried to search for this but can't find what I am looking for.

I would like to find a program to estimate how much horsepower my engine is producing. I have found some that will tell you, if I had a distance and time (1/4 mile @ 12 sec type of equation). I don't have that info and it is not easily(ie: legally) produced. I would to get a base horsepower to know in which direction I would like to go.

Is there something that if I input information like, cam specs, carb, bore and stroke,head specs... It will spit out a horsepower number?
